Wiseco SK1316 Forged Piston Kit for Arctic Cat Snowmobiles

The Wiseco SK1316 is a high-performance forged piston kit engineered specifically for Arctic Cat snowmobiles. Designed and manufactured entirely in the USA, this piston kit delivers the strength, precision, and durability demanded by snocross and cross-country racing applications.

USA Forged Construction:

Wiseco forges all of its pistons in-house using proprietary forge tooling produced at their own facility. This end-to-end manufacturing control — from raw bar stock to finished skirt-coated parts — ensures consistent quality and tight tolerances that off-the-shelf cast pistons simply cannot match.

Key Features:

• Forged aluminum construction — denser grain structure aligned to part geometry for superior mechanical properties
• Skirt coating — factory-applied coating reduces friction and improves break-in performance
• High strength-to-weight ratio — optimized forging geometry maximizes power output while minimizing reciprocating mass
• Impact and fatigue resistance — forged grain structure resists cracking and deformation under extreme loads
• In-house dyno validated — developed and tested on Wiseco's own dynamometers for proven performance gains
• Designed for Arctic Cat applications — engineered to OEM specifications for proper fit and function

Unlike cast pistons, which have no defined grain structure and are prone to sudden catastrophic failure when material yield strength is exceeded, Wiseco forgings feature a condensed, aligned grain structure that provides greater resistance to the shock, heat, and mechanical stress of high-performance snowmobile racing. This makes the SK1316 an ideal upgrade or replacement for riders pushing their Arctic Cat sleds to the limit.
